EGG-TRAY FOR INCUBATORS.

SPECIFICATION forming part of Letters Patent No. 588,044, dated August10, 1897.

Application filed May 27, 1896. Serial No. 593,313. (No model.)

T ail whom it nut l (JO/Z6877."

Be it known that I, JOHN H. YOUNG, a citizen of the United States,residing at Rantoul, in the county of Franklin and State of Kansas, haveinvented certain new and useful Improvements in Egg-Trays forIncubators; and I do declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to 1 0 which it appertains to make and use the same.

My invention has relation to trays for holdin g the eggs in incubators,and more particularly to that class in which all of the eggs in the traycan be turned over half-Way, as is done by the mother hen, withoutremoving them from the incubator or even handling them; and the objectof my invention is to provide a simple, safe, and convenient device ofthis class, as will be hereinafter more fully described, andparticularly pointed out in the claims.

In the accompanying drawings the same figures of reference indicate thesame parts of the invention.

Figure 1 is a perspective view of a section of an incubator with myimproved tray in place. Fig. 2 is a view of the tray removed from theincubator. Fig. 3 is a longitudinal section of the tray, showing theeggs in place.

0 Fig. 4 is a view of one of the sides of the tray.

Fig. 5 is a perspective view of the roller-frame removed from the tray,and Fig. 6 is an enlarged cross-section of the same.

The egg-tray 2 consists of two end pieces 5 3 at and two side pieces 56, secured together in the form of a rectangle. The side pieces 5 and 6are provided with longitudinal rectangular grooves 7, located near theirlower edges, and in these grooves 7 the sides 8 8 of 0 the rectangularroller-frame S S 9 9 freely slide, the length of the outside of therollerframe being shorter than the inside length of the egg-tray toallow the frame to have an end'movement within the tray of two or threeThe front end 9' of said frame is provided with two rods 10 10, securedthereto,

and their outer ends have each a removable knob or handle 12, whichextends outside of the wall 13 of the incubator, the rods 10 10 passingthrough orifices 14 in said Walls.

A series of rollers 15 are journaled in the sides 8 8 of the rectangularframe and over them is a piece of cloth 16, the ends 17 of which areprovided with cords 18 and are secured in place by cleats 19 19, securedto the ends 3 4 of the tray proper, there being sufficient material toallow the cloth to sag down by the weight of the eggs between therollers.

The eggs being placed in the tray on the cloth resting on the rollers,the tray is then inserted in the incubator, with the rods 10 1Oprojecting through the orifices in the walls. The knobs 12 12 are thensecured in place and the door closed. Whenever it is necessary to turnthe eggs without opening the door and letting cold air in, the knobs arepushed in, which slides the frame containing the eggs in the tray. Thismotion causes the rollers to turn the eggs one-half way around the same,as a hen does, and as they have to be turned every twelve hours the nexttime it is necessary to turn them the knobs are simply pulled out,restoring them to their former position, and so on until the hatch isfinished.

Although I have specifically described the construction and relativearrangement of the several elements of my invention, I do notdesire tobe confined to the same, as such changes or modifications may be made asclearly fall within the scope of my invention Without departing from thespirit thereof.

Having thus fully described my invention, what I claim as new anduseful, and desire to secure by Letters Patent, is

l. The combination with an egg-tray, of a roller-frame forming thebottom of said tray and having a sliding engagement therewith, and aflexible belt or fabric secured to said tray and supported upon saidrollers with portions thereof sagging between said rollers to formegg-pockets, substantially as set forth.

2. The combination with an egg-tray having grooves in the inner faces ofits sides, of a roller-frame forming the bottom of said tray and havingits sides seated in said grooves, the length of the outside of theroller-frame being less than the length of the inside of the the ends ofthe belt or fabric to the cleats,

tray, means for moving the ro11er-fra1ne, a substantially as set forth.no flexible belt or fabric supported on the rollers In testimony whereofI hereunto affix my of the roller-frame and being of a greater signaturein presence of two witnesses.

5 length than the roller-frame so that portions of said belt or fabricwill sag between said Vitnesses: rollers and form egg-pockets, cleatssecured J. M. SPRINGER, to the ends of the tray, and cords connecting I.F. GORTHY.
